Double Glazed Units

We are specialists in manufacturing Double Glazed Units, otherwise known as DGU’s. We offer high quality, competitively priced DGU’s which are manufactured at our Norwich factories and delivered across Norfolk, Suffolk and Cambridge on a regular basis.

For many households, installing double glazing will mean smaller energy bills and a warmer home. But it’s a big expense, so you want to make the right decision for your home.

Is double glazing effective

Double glazed units consist of two panes of glass separated by a layer of air or gas. Double glazed units have many benefits over single glazing (where there’s just one pane of glass and no air layer or gas):

• Keeps warm air in, meaning your property is better insulated. This results in fewer draughts and cheaper heating bills.
• Keeps noise out – you’ll hear less noise from outside with double glazing.
• Reduces the amount of condensation on the inside of your windows.
• Heightens security – double glazed glass is more difficult to break than single glazing.

The most efficient double glazing has gas between the panes (such as argon), and uses low-emissitivy glass (Low-E), which has a reflective coating to help bounce sunlight back into a home.

Will getting double glazed units reduce my energy bills?

If all of the single-glazed windows were replaced in a detached house with A++ double glazed windows, the Energy Saving Trust says that you’d save between £110 and £115 per year. For a mid-terraced house, where it is attached on both sides and so would naturally use and lose less heat, it would be £60.

When Do Double Glazed Units Need Replacing?

If you’re unsure whether your windows need replacing, these signs should help you decide:

• They are letting water in.
• You can feel wind coming through.
• They allowing noise in.
• They are damaged, particularly to the seals.
• They uPVC is yellowing or timber is cracking
• They’re difficult to open, close and lock, or are sticking.
• Condensation between the panes of glass.

Condensation on a double glazed window or door can be a sign that it needs replacing. However in rare cases, new double glazing can cause damp. Homes need to have some ventilation. Older buildings are built to breathe, so adding lots of energy-saving measures stops moisture in the air from escaping. In the winter, when it’s warm inside and cold out moisture can collect on the glass. To try and avoid any problems, when getting new double glazing units, make sure you think about the ventilation in that room. One way to enable a small amount of air in and moisture out is to have trickle vents in the frames of your double glazed units.  You could also consider two small windows instead of one big. This could ley a little air in at any one time. Some windows also allow you to lock them slightly open.

Our double glazes units can be made to almost any specification including shaped and bent glass. We offer a wide range of products which can be used in the manufacturing of Double Glazed Units, including glass for solar reflection, heat retention, self cleaning and much more. We also manufacture DGU’s that require made to measure pre-cut holes for cat/dog flaps or gas vents.
